Sunflower - FAQ

Could the sunflower give me a sunburn?


No. Sunburns are a type of tissue damage that is caused by ultraviolet light. The sunflower only contains red and near-infrared wavelengths which are unable to inflict the type of cellular damage that causes sunburn.




How does my light routine actually reduce pain?


Light routines, or photobiomodulation, create positive biological effects through multiple different mechanisms depending on where the light is absorbed. The main mechanism that causes pain relief is photobiomudlation’s ability to reduce proinflammatory cytokines, which reduces overall inflammation. A reduction in inflammation causes pain to subside.




Are there any side effects of my Just Light routine?


Photobiomodulation (PBM) is regarded as safe and painless; without side effects. Due to the biphasic nature of the PBM, it is possible to receive too much red and near-infrared which can nullify it’s positive benefits. However, if you stick within the recommended JustLight routines you will not be at risk for too much light exposure.




I completed a JustLight routine on my face and my vision looks distorted. Did the light damage my eyes?


It is normal and safe to experience a temporary color distortion after your eyes are exposed to intense red light. This occurs because the red cones in your eyes become temporarily less sensitive to adjust to the intense red light. When the red light exposure ends, the blue and green cones are more sensitive compared to the red cones, which causes everything in your visual field to have color distortion. This effect will not last longer than a couple of minutes.




Do I need to wear eye protection?


Only in the cases of specific JustLight routines that recommend eye protection. Regardless, do not stare directly into the LEDs and always keep your eyes closed while doing face treatments.




I have more questions!


We love questions! Sunflower utliizes a lot of complex science and non-intuitive photochemical interactions. Please email any questions to info@JustLight.com and we will add our answer to the FAQ!




What is Near-Infrared light (NIR)?


Short Answer: NIR Light is deeper penetrating than Red Light with all the same benefits, but invisible to human eyes.
The Science A: Humans can view a spectrum from violet (~400nm) to Red (~760nm). Near infrared light exists in the 800-1400 nm wavelength, just outside of the visible spectrum. NIR is used in light routines because it has a similar mechanism of action as red light does but it penetrates deeper into the body. NIR and infrared light can often be felt as heat, which is why you may feel warmth coming from your Sunflower.




How does photobiomodulation (PBM) work?


Short Answer: Red and near infrared light increases cellular energy, promotes healing pathways, and removes waste.
The Science: To understand the biological effects of light we must first look at how a cell produces energy with its mitochondria. Mitochondria use the food we eat and the air we breathe to produce adenosine triphosphate(ATP) which acts as the energy source for the cell. This can be interrupted by nitric oxide(NO), a chemical byproduct of many cellular processes. NO binds to the enzyme cytochrome c oxidase(CCO) inhibiting its intake of oxygen and consequently reducing its production of ATP by nearly 90%. Red and near-infrared light is absorbed by CCO which dissociates NO and dramatically increases ATP production. The increased activity of the CCO also produces a small amount of reactive oxygen species(ROS), which activates transcription factors for genes that promote cellular healing and repair. In other words, the ROS acts as an alarm bell signaling the cell to focus on healing. Together these mechanisms give a cell the instructions to focus on healing and the additional energy to carry out these processes.




Does red light work through clothing?


Although a small amount of light can penetrate through clothing, we recommend that all sessions be performed onto bare skin. The calculations that govern Sunflower's automated light cycle are operating on the assumption that the are being treated is bare, exposed, skin.

Lotus - FAQ

What’s the difference between the Lotus Bulb and the Sunflower?


The Lotus Bulb is a simple light therapy device that contains the bare minimum for an effective light routine. The Sunflower is a software integrated device that enables precision light therapy with a more powerful and diverse array of LEDs. The Sunflower is still in development, but we knew that no one should have to wait to start feeling the benefits of light. That’s why we are selling Lotus Bulbs today, so you can start your JustLight routines as soon as possible.




What can I use the Lotus Bulb for?


The Lotus Bulb emits powerful red and near-infrared light allowing it to support skin health, repair wounds, improve cognitive functioning, alleviate pain, and increase muscle performance.




How do I use the Lotus Bulb?


Hold or secure the Lotus Bulb about 6 inches away from the area you would like to experience the benefits of light. To support skin health and wound repair shine the Lotus Bulb on the targeted area for about 3 minutes. To alleviate pain or increase muscle performance, shine the Lotus Bulb on a joint or muscle for about 12 minutes. To improve cognitive functioning and mood, shine the Lotus Bulb on your forehead for about 20 minutes. If you experience any visual discomfort during this process it is recommended that you use eye protection.




Why do I feel heat coming out of the Lotus Bulb?


The Lotus Bulb emits near-infrared light which is felt by the body as heat. The Lotus Bulb may also become hot if it has been running for a while, so be careful with the Lotus Bulb during long sessions.




Why do I only see 9 lights, are the others broken?


The Lotus Bulb contains 9 visible red LEDs and 9 near-infrared LEDs which are invisible to the human eye.
